3、取水工程设计、给水管网设计和净水厂设计。该净水厂处理工艺采用常规处理，即“混凝沉淀过滤消毒”。 设计水厂建于城市的东北角，靠近城市和水源地。混凝包括混合和絮凝两部分。取水工程中采用地表水做水源，根据水位变化较大，水厂采用固定式取水构筑物。由于主流近岸，岸边有足够的水深，水质地质条件较好，所以选择岸边式取水构筑物。一泵站选取水泵250S24A型单级双吸离心泵四台，三用一备。混凝采用PAFC，计量泵投加，选三台AHC62计量泵，设计流量为108 L/h，两用一备，单台泵流量为Q=105L/h。溶液池分三个格，每格容积为13m3，两用一备交替使用。 溶解池分三格，每格容积为2.6m3，两用一备交替使
4、用。设计尺寸：LBH=1.5m1.5m1.5m，包括超高0.3m。设计尺寸：LBH=2.4m3m2.1m，包括超高0.3m。絮凝池采用网格絮凝池，分为4组，絮凝池的有效水深3.6m池的总高H为4.4m，单个有效尺寸为1.391.39米。沉淀池采用斜管沉淀池，分2组，尺寸1430m，为了配水均匀，进水区布置在30长的一侧。池子总高度H为4.67m，取5m。沉淀池进口采用穿孔墙，排泥采用穿孔管，集水系统采用穿孔管。滤池采用V型滤池，为2个双格滤池。反冲洗使用气水反冲洗，反冲洗水泵选择泵型号700HQB50D，选六台，四用两备。选择DG型离心鼓风机，选用八台，六用两备。消毒使用液氯消毒，滤池有效工作
5、时间T=24-240.2/48=23.9h，滤池高度3.9m。加氯量Q为3.831kg/h。采用加氯机投氯，本设计选用2J型-2转子加氯机两台，交替使用。清水池设为两座，每座的容积为1/2W=6500m3,尺寸采用40m40m4.5m。二泵站设计中，选四台350S125型泵，三台工作，一台备用，为调节用水不均匀性，其中一台水泵设置变频调速装置。采用连续式重力浓缩池，设计2座，每个浓缩池面积335.2m2，浓缩池总高度5.8m。取6m。本给水工程设计能够缓解大同市用水需求，符合其经济、工业水平的不断发展要求，也有利于大同市的进一步发展要求。关键词 管网平差；取水工程；净水厂设计AbstractT
